Flora of North America species comparison

few to several, erect or ascending, sometimes decumbent at base, unbranched or branched, hairs spreading to retrorse, short, scabrid below inflorescence, sometimes becoming medium length to long, soft to stiff, mixed with short stipitate-glandular ones in inflorescence.

few to many, erect or ascending, much-branched with many short, leafy axillary shoots, hairs recurved to retrorse, short, ± stiff, eglandular, often with some spreading, long ones.

green, sometimes purplish, linear to lanceolate or narrowly oblong, 1–8.5 cm, not fleshy, margins plane, flat or involute lengthwise, 0(–5)-lobed, apex acute;

lobes ascending, linear, central one sometimes shallowly toothed, apex acute to obtuse.

green, linear-lanceolate to lanceolate, 1–3.5 cm, not fleshy, margins plane, sometimes ± wavy, flat to involute, (0–)3–7-lobed, apex acute to obtuse;

lateral lobes spreading, linear, much shorter and narrower than terminal lobe, apex acute.

3–14 × 1.5–3 cm;

bracts greenish throughout, or proximally greenish, distally pale to bright yellow or whitish, rarely pale orangish, lanceolate to oblong, (0–)3–7-lobed;

lobes ascending to erect, linear to lanceolate or narrowly oblong, medium length, arising at or above mid length, central lobe apex obtuse to rounded, lateral ones acute.
